摘　　要：临沂污水厂原设计规模为15×104m3/d,一期工程(8×104m3/d)采用底曝氧化沟工艺,二期工程(7×104m3/d)采用A/A/O工艺,总排口出水水质基本达到一级B标准。此次升级改造,将原一期工程的底曝氧化沟改造成复合式好氧池,并配套前置缺氧池,对原二期工程的厌氧段、缺氧段进行水力优化,增加转盘式过滤器,使出水水质达到一级A排放标准,不需另外征地,可为类似污水处理厂升级改造提供参考。The original design capacity of Linyi WWTP was 15×104 m3/d,the first-phase project(8×104 m3/d) with the bottom aeration oxidation ditch process,the second-phase project(7×104 m3/d) with A/A/O process,the effluent quality at the general outlet basically reached the first level B criteria.In the upgrading and reconstruction project,the bottom aeration oxidation ditch is reconstructed into a compound aerobic tank with pre-anoxic tank,and the anaerobic stage and the anoxic stage are hydraulically optimized.The ...
